Timely Tendings: fall vegetable gardening

Go ahead and plant cool season veggies

This month is a great time to plant cool season vegetable crops such as broccoli, cabbage, celery, lettuce, onions and peas. If you have not yet prepared for your fall vegetable garden, it's not too late to get started now. By using transplants from your local garden center you can get your garden off to a faster start. For all you need to know about vegetable gardening in Florida, see the Florida Vegetable Gardening Guide at edis.ifas.ufl.edu/pdffiles/VH/VH02100.pdf.

Some suggested varieties of these cool season veggies include:

Broccoli: Early Green Sprouting, Waltham 29, Atlantic, Green Comet, Green Duke

Cabbage: Gourmet, Marion Market, King Cole, Market Prize, Red Acre, Chieftain Savoy, Rio Verde, Bravo

Celery: Utah Strains, Florida Strains, Summer Pascal

Divide perennials, bulbs in flower beds

September is a good month to rejuvenate your flower beds for the fall and winter growing seasons. Now is a good time to divide and plant bulbs and perennials. There are three reasons to divide perennials: to control the size of the plants, to help rejuvenate them so that they keep blooming and to increase their number.

Gingers are among our finest perennial plants. During the summer months, they have produced an abundance of growth. To ensure good growth next year, dig up and divide rhizomes. Shell ginger (Alpinia zerumbet) is a vigorous grower that produces magnificent pinkish, shell-shaped flowers looking much like a cluster of grapes.

Propagation of the ginger is easy. Dig up a rhizome and cut it, leaving an immature sprout or two on each section. The rhizomes should be planted only about 2 to 3 inches deep. The gingers require little care other than moist soil, afternoon shade and occasional fertilization. (Always check your local ordinances before fertilizing.)

Day lilies (Hemerocallis spp.), which have grown prolifically during the summer months, are now beginning a short period of dormancy. As day lilies age, they produce a thick clump of growth over time that can result in weak plants that do not bloom well. Divide them by digging up the entire clump. Then separate each individual plant or fan, and replant them a little higher than they were in the original clump. There will be large tuberlike growths on the root system. Do not remove these storage organs that help to promote further growth.

Stokes aster (Stokesia laevis) is another perennial that has a tendency to become too dense, so it should be divided now. The long, large roots may be reduced to make transplanting easier. As with the day lilies, there are many plants within the clump. They should be separated and set slightly higher than their original depth.

This is also the time of year to dig bulbs. Separate and plant the small bulbs that form around the large central bulb, then replant the older bulb. Amaryllis (Hippeastrum) has a tendency to draw its bulbs into the ground. When replanting, make sure that the top third of the bulb is exposed to ensure blooms. This applies to other bulbs in the Amaryllis family, such as spider lily and alligator lily (Hymenocallis spp.) and rain lily (Zephyranthes spp.). The large native Crinum or swamp lily (Crinum americanum) can also be divided now.
